Question

Genes that are close together in the same chromosome:_________
A. tend to assort independently.
B. assort primarily independently, but will, very rarely, be transmitted together.
C. tend to be transmitted together.
D. tend to be transmitted together, and are present only in X chromosomes.
E. are present only in X chromosomes.

Answer 1

Answer:

C. tend to be transmitted together.

Explanation:

Independent assortment of alleles of the genes during anaphase-I of meiosis-I requires that the genes should be present on different chromosomes. The genes that are present on the same chromosomes deviate from the independent assortment. These closely placed genes are called linked genes. They move from one generation to next together and do segregate randomly. This results in the generation of more proportion of the parental types in the progeny. The linked genes may be present on both autosomes and sex chromosomes.
